Submarine Telegraph Cables which have been successful for some Time, but are not now working.

Table III

Submarine Telegraph Cables Which Are Total Failures.

It will be seen from the above list of failures, that the great extension and success of submarine cables has been attained through many great failure,—among the most prominent being the old and new Atlantic, the Red Sea and India, (which was laid in five sections, that worked from six to nine months each, but was never in working order from end to end,) the Singapore and Batavia, and Sardinia and Corfu. None of these cable, with the exception of the new Atlantic, were tested under water after manufacture, and every one of them was covered with a sheathing of light iron wire, weighing in the aggregate only about fifteen hundred pounds per mile.

These two peculiarities are sufficient to account for every failure which has occurred, with the exception of the new Atlantic. No electrical test will show the presence of flaws in the insulating cover of a wire, unless water, or some other conductor, enters the flaws and establishes an electrical connection between the outside and inside of the cable. All cables now manufactured are tested under water before being laid.

Communication between the Ottoman capital and Western Europe passes through Vienna. From this city to Constantinople there are two distinct lines,—one passing by Semlin and Belgrade to Adrianople, the other by Toultcha, Kustendji, and Varna. There is a third line to Adrianople by Bucharest; and by the opening of the submarine line between Avlona and Otranto, in Italy, the Turkish telegraph service will be in direct communication with the West, without going through Servia or the Moldo-Wallachian Principalities.

Communication between Constantinople and India is maintained over the following route:—To Ismid, 55 miles; thence to Mudurli, 104 miles; thence to Angora, 111 miles; thence to Guzgat, 113 miles; thence to Sivas, 140 miles; Kharpoot, 178 miles; Diarbekir, 77 miles; Mardeen, 61 miles; Djezireh, 104 miles; Mosul, (Nineveh,) 91 miles; Kerkook, 114 miles; Bagdad, 189 miles. From Bagdad to Fao, at the mouth of the Shat-el-Arab, on the Persian Gulf, is 400 miles. From Fao to Kurrachee the submarine cable stretches along the bottom of the Persian Gulf for 1,450 miles; and thence are 500 miles of aërial line across a portion of British India to Bombay.

The accounts of the successful opening of this line tell of the astonishment of the savage Beloochees and Arabs along the Mekran coast at the marvel of a blue spark flashing for the Sahib to the Indus and back again in less time than it takes to smoke a hookah. At Gwadur, no sooner was the cable landed than the people of the surrounding country flocked down to hear and talk of the Feringhee witchcraft. Chiefs of the Beloochees, Muscatees, and Heratees, with their retainers, trod upon each other's toes in their eagerness to see it work. Gwadur has given up the idea that Mahomet taught everything that could be known, and now sits upon the carpet of astonishment and chews the betel-nut of meditation.

The establishment of the electric telegraph in India presented some curious as well as difficult problems. In the first place, it was discovered that the air of India is in a state of constant electrical perturbation of the strongest kind, so that the instruments there mounted went into a high fever and refused to work. Along the north and south lines a current of electricity was constantly passing, which threw the needles out of gear and baffled the signallers. Moreover, the tremendous thunder-storms ran up and down the wires and melted the conductors; the monsoon winds tore the teak-posts out of the sodden ground; the elephants and buffaloes trampled the fallen lines into kinks and tangles; the Delta aborigines carried off the timber supports for fuel, and the wires or iron rods upon them to make bracelets and to supply the Hindoo smitheries; the cotton- and rice-boats, kedging up and down the river, dragged the subaqueous wires to the surface. In addition to these graver difficulties were many of an amusing character. Wild pigs and tigers scratched their skins against the posts in the jungle, and porcupines and bandicoots burrowed them out of the ground. Kites, fishing-eagles, and hooded-crows came in hundreds and perched upon the line to see what on earth it could mean, and sometimes after a thunder-storm, when the wires were wet, were found dead by dozens, the victims of their curiosity, Monkeys climbed the posts and ran along the lines, chattering, and dropping an interfering tail from one wire to another, which tended to confound the conversations of Calcutta. Parrots, with the same contempt for electrical insulation, fastened upon one string by the beak and another by the leg; and in one village, the complacent natives hung their fishing-lines to dry upon them.

In 1856 there were four thousand miles of telegraph-wire stretched over India: some upon bamboo posts, which bent to the storms and thus defied them; some, as in the Madras Presidency, upon monoliths of granite,—these, during the Mutiny, proving worth ten times their cost.

Whilst the telegraph has been thus rapidly encircling the globe with its iron threads, great improvement has been made in the apparatus for transmitting the electrical signals over them. Instruments called translators, or repeaters, have been devised, by which aërial lines may be operated, without repetition, over distances of many thousands of miles. Through the use of this valuable invention upon the California line, operators in New York and San Francisco are able to converse as readily and rapidly as those situated at the extremities of a line only a hundred miles in length.

The enormous increase in the amount of matter to be transmitted over the wires has stimulated the inventive genius of our own country and Europe to produce an apparatus by which the capacity of a wire may be greatly increased. Mr. M. G. Farmer of Boston, Mr. J. G. Smith of Portland, Maine, Dr. Gintl of Germany, and one or two other persons, have solved the problem of the simultaneous transmission of messages over a single wire in opposite directions. But while their apparatus, with the proper arrangement of batteries, will unquestionably permit the accomplishment of this apparent paradox, the natural disturbances upon a wire of any considerable length, together with the inequalities of the current caused by escape in wet weather, have precluded its practical use.

In this country, General Lefferts of New York, and in Europe, Professor Bonelli, have devoted much time and expense to the perfection of apparatus for securing greater rapidity of transmission over the aërial lines.

General Lefferts owns several patents covering inventions of great ingenuity and value, which are now being perfected and will shortly be brought into operation. The apparatus consists of an instrument, operated by keys similar to those of a piano-forte, for punching characters, composed of dots and lines, upon a narrow strip of paper. The paper, when thus prepared, is passed rapidly through an instrument attached to a telegraph-wire, at the other end of which is a similar instrument which runs in unison. The first instrument is provided with a flexible metallic comb, which presses through the perforations in the paper and thus closes the circuit at each dot and line, while the second instrument is provided with a metallic stylus, or pointer, which rests upon a fillet of paper prepared with chemicals, and produces, whenever the circuit is closed, dots and lines of a dark blue color upon the prepared paper. When the paper is prepared by the perforating apparatus, it can be run through the instrument at any rate of speed that is desirable, and it is estimated that with this apparatus one wire may easily perform as much work in a day as ten can under the ordinary arrangement.

In Professor Bonelli's system the dispatch is set up in printing-type, and placed on a little carriage, which is made to pass beneath a comb with five teeth, which are in communication with five aërial wires of the line, at the extremity of which these same wires are joined to the five teeth of a second comb, under which passes a chemically prepared paper, carried along on a little carriage similar to the one at the other end on which the printing-type is placed. If under this arrangement the electric circuit of a battery composed of a sufficient number of elements, and distributed in a certain order, be completed, then, at the same time that the first comb is passing over the printing-type at the one end, the second comb at the other end will trace the dispatch on the prepared paper in beautiful Roman letters, and with so great a rapidity that it may be expected that five hundred messages of twenty words each will be transmitted hourly.

On Wednesday, April 19th, the day of Mr. Lincoln's funeral, eighty-five thousand words of reports were transmitted between Washington and New York, between the hours of 7, p. m., and 1, a. m., being at the rate of over fourteen thousand words per hour. Nine wires were employed for the purpose. Thirteen thousand six hundred words were transmitted by the House printing instruments on a single wire after half past seven o'clock.

A telegraphic message was recently received in London from India in eight hours and a half. This message was forwarded by the Indo-European Telegraph Company, viâ Kurrachee and the Persian Gulf, crossing one half of Asia and the whole of Europe.

During the late Rebellion in this country the telegraph was extensively employed both by the Government and the Insurgents. In the course of the past year, there have been in the service of the Government thirty field-trains, distributed as follows:—In the Army of the Potomac, five; in the Department of the Cumberland, five; in the Department of the Gulf, three; in the Department of North Carolina and Virginia, three; in the Department of the South, two; in the Department of the Tennessee, six; in the Department of the Ohio, two; at the Signal Camp of Instruction, Georgetown, D. C., three; at the United States Military Academy, West Point, New York, one. Of these trains, some were equipped with five, and others with ten miles of insulated wire. There were carried in the trains lances for setting up the wire, when necessary,—reels, portable by hand, carrying wire made purposely flexible for this particular use,—and various minor appliances, which experience has proved useful. A military organization was directed for each train.

In duty of this kind, the construction of the trains, the equipment to be carried by them, and the military organization to be provided for their use, to enable them to be most rapidly and anywhere brought into action, are the subjects for study: the particular instrument to be equipped is a secondary consideration. The soldiers drilled to the duty of construction acquire in a short time a remarkable skill in the rapid extension of these lines. As was anticipated, they have proved valuable auxiliaries to the services of the corps, and have sometimes rendered them available when they would have been otherwise useless. The greatest distance at which the instruments are reported to have worked is twenty miles. The average distances at which they are used are from five to eight miles. The average speed of the most rapid construction is reported to be at the rate of a slow walk.

At the first Battle of Fredericksburg field-trains were for the first time in the history of the war used on the battle-field, under the fire of the enemy's batteries. The movements to be made on the day of that battle were of the first magnitude. The movements of the retreat were perilous to the whole army. The trains in use contributed something to the success of those movements.

Many incidents are recorded of operators accompanying raiding parties into the enemy's territory and tapping the telegraph-lines, sometimes obtaining valuable information. One is related by the "Selma Rebel." The operator at that place was called to his instrument by some one up the Tennessee and Alabama Road, who desired information as to the number of the forces and supplies at Coosa Bridge. After getting all the information he could, regarding the location and strength of the Rebel forces, he informed the Selma operator that he was attached to the expedition under General Wilson, and that, at that particular time, he was stationed with his instruments up a tree near Monticello, in the hardest rain he ever saw! Permission being given, he sent a dispatch to a young lady in Mobile, and another to a telegraph-operator in the Rebel lines, telling him he loved him as much as before the war. After some other conversation, the Yankee operator clambered down from the tree, mounted his horse, and rode away.

FOOTNOTES:

THE FIELD OF GETTYSBURG

In the month of August, 1865, I set out to visit some of the scenes of the great conflict through which the country has lately passed.

On the twelfth, I reached Harrisburg,—a plain, prosaic town of brick and wood, with nothing especially attractive about it, except its broad-sheeted, shining river, flowing down from the Blue Ridge, around wooded islands, and between pleasant shores.

It is in this region that the traveller from the North first meets with indications of recent actual war. The Susquehanna, on the eastern shore of which the city stands, forms the northern limit of Rebel military operations. The "highwater mark of the Rebellion" is here: along these banks its uttermost ripples died. The bluffs opposite the town are still crested with the hastily constructed breastworks, on which the citizens worked night and day in the pleasant month of June, 1863, throwing up, as it were, a dike against the tide of invasion. These defences were of no practical value. They were unfinished when the Rebels appeared in force in the vicinity. Harrisburg might easily have been taken, and a way opened into the heart of the North. But a Power greater than man's ruled the event. The Power that lifted these azure hills, and spread out the green valleys, and hollowed a passage for the stream, appointed to treason also a limit and a term. "Thus far, and no farther."

The surrounding country is full of lively reminiscences of those terrible times. Panic-stricken populations flying at the approach of the enemy; whole families fugitive from homes none thought of defending; flocks and herds, horses, wagon-loads of promiscuously heaped household stuffs and farm produce; men, women, children, riding, walking, running, driving or leading their bewildered four-footed chattels,—all rushing forward with clamor and alarm under clouds of dust, crowding every road to the river, and thundering across the long bridges regardless of the "five-dollars-fine" notice (though it is to be hoped that the toll-takers did their duty):—such were the scenes which occurred to render the Rebel invasion memorable. The thrifty German farmers of the lower counties did not gain much credit either for courage or patriotism at that time. It was a panic, however, to which almost any community would have been liable. Stuart's famous raid of the previous year was well remembered. If a small cavalry force had swept from their track through a circuit of about sixty miles over two thousand horses, what was to be expected from Lee's whole army? Resistance to the formidable advance of one hundred thousand disciplined troops was of course out of the question. The slowness, however, with which the people responded to the State's almost frantic calls for volunteers was in singular contrast with the alacrity each man showed to run off his horses and get his goods out of Rebel reach.

From Harrisburg, I went, by the way of York and Hanover, to Gettysburg. Having hastily secured a room at a hotel in the Square, (the citizens call it the "Di'mond,") I inquired the way to the battle-ground.

"You are on it now," said the landlord, with proud satisfaction,—for it is not every man that lives, much less keeps a tavern, on the field of a world-famous fight. "I tell you the truth," said he; and, in proof of his words, (as if the fact were too wonderful to be believed without proof,) he showed me a Rebel shell imbedded in the brick wall of a house close by. (N. B. The battle-field was put into the bill.)

Gettysburg is the capital of Adams County: a town of about three thousand souls,—or fifteen hundred, according to John Burns, who assured me that half the population were Copperheads, and that they had no souls. It is pleasantly situated on the swells of a fine undulating country, drained by the headwaters of the Monocacy. It has no special natural advantages,—owing its existence, probably, to the mere fact that several important roads found it convenient to meet at this point, to which accident also is due its historical renown. The circumstance which made it a burg made it likewise a battle-field.

About the town itself there is nothing very interesting. It consists chiefly of two-story houses of wood and brick, in dull rows, with thresholds but little elevated above the street. Rarely a front yard or blooming garden-plot relieves the dreary monotony. Occasionally there is a three-story house, comfortable, no doubt and sufficiently expensive, about which the one thing remarkable is the total absence of taste in its construction. In this respect Gettysburg is but a fair sample of a large class of American towns, the builders of which seem never once to have been conscious that there exists such a thing as beauty.

John Burns, known as "the hero of Gettysburg," was almost the first person whose acquaintance I made. He was sitting under the thick shade of an English elm in front of the tavern. The landlord introduced him as "the old man who took his gun and went into the first day's fight." He rose to his feet and received me with sturdy politeness,—his evident delight in the celebrity he enjoys twinkling through the veil of a naturally modest demeanor.

"John will go with you and show you the different parts of the battle-ground," said the landlord. "Will you, John?"

"Oh, yes, I'll go," said John, quite readily; and we set out at once.

A mile south of the town is Cemetery Hill, the head and front of an important ridge, running two miles farther south to Round Top,—the ridge held by General Meade's army during the great battles. The Rebels attacked on three sides,—on the west, on the north, and on the east; breaking their forces in vain upon this tremendous wedge, of which Cemetery Hill may be considered the point. A portion of Ewell's Corps had passed through the town several days before, and neglected to secure that very commanding position. Was it mere accident, or something more, which thus gave the key to the country into our hands, and led the invaders, alarmed by Meade's vigorous pursuit, to fall back and fight the decisive battle here?

With the old "hero" at my side pointing out the various points of interest, I ascended Cemetery Hill. The view from the top is beautiful and striking. On the north and east is spread a finely variegated farm country; on the west, with woods and valleys and sunny slopes between, rise the summits of the Blue Ridge.

It was a soft and peaceful summer day. There was scarce a sound to break the stillness, save the shrill note of the locust, and the perpetual click-click of the stone-cutters, at work upon the granite headstones of the soldiers' cemetery. There was nothing to indicate to a stranger that so tranquil a spot had ever been a scene of strife. We were walking in the time-hallowed place of the dead, by whose side the martyr-soldiers, who fought so bravely and so well on those terrible first days of July, slept as sweetly and securely as they.

"It don't look here as it did after the battle," said John Burns. "Sad work was made with the tombstones. The ground was all covered with dead horses, and broken wagons, and pieces of shells, and battered muskets, and everything of that kind, not to speak of the heaps of dead." But now the tombstones have been replaced, the neat iron fences have been mostly repaired, and scarcely a vestige of the fight remains. Only the burial-places of the slain are there. Thirty-five hundred and sixty slaughtered Union soldiers lie on the field of Gettysburg. This number does not include those whose bodies have been claimed by friends and removed.

The new cemetery, devoted to the patriot slain, and dedicated with fitting ceremonies on the 19th of November, 1863, adjoins the old one. In the centre is the spot reserved for the monument, the corner-stone of which was laid on the 4th of July, 1865. The cemetery is semicircular, in the form of an amphitheatre, except that the slope is reversed, the monument occupying the highest place. The granite headstones resemble rows of semicircular seats. Side by side, with two feet of ground allotted to each, and with their heads towards the monument, rest the three thousand five hundred and sixty. The name of each, when it could be ascertained, together with the number of the company and regiment in which he served, is lettered on the granite at his head. But the barbarous practice of stripping such of our dead as fell into their hands, in which the Rebels indulged here as elsewhere, rendered it impossible to identify large numbers. The headstones of these are lettered, "Unknown." At the time when I visited the cemetery, the sections containing most of the unknown had not yet received their headstones, and their resting-places were indicated by a forest of stakes. I have seen few sadder sights.

The spectacle of so large a field crowded with the graves of the slain brings home to the heart an overpowering sense of the horror and wickedness of war. Yet, as I have said, not all our dead are here. None of the Rebel dead are here. Not one of those who fell on other fields, or died in hospitals and prisons in those States where the war was chiefly waged,—not one out of those innumerable martyred hosts lies on this pleasant hill. The bodies of once living and brave men, slowly mouldering to dust in this sanctified soil, form but a small, a single sheaf from that great recent harvest reaped by Death with the sickle of war.

Once living and brave! How full of life, how full of unflinching courage and fiery zeal, they marched up hither to fight the great fight, and to give their lives! And each man had his history; each soldier resting here had his interests, his loves, his darling hopes, the same as you or I. All were laid down with his life. It was no trifle to him, it was as great a thing to him as it would be to you, thus to be cut off from all things dear in this world, and to drop at once into a vague eternity. Grown accustomed to the waste of life through years of war, we learn to think too lightly of such sacrifices. "So many killed,"—with that brief sentence we glide over the unimaginably fearful fact, and pass on to other details. We indulge in pious commonplaces,—"They have gone to a better world, they have their reward," and the like. No doubt this is true; if not, then life is a mockery, and hope a lie. But the future, with all our faith, is vague and uncertain. It lies before us like one of those unidentified heroes, hidden from sight, deep-buried, mysterious, its headstone lettered "Unknown." Will it ever rise? Through trouble, toils, and privations,—not insensible to danger, but braving it,—these men—and not these only, but the uncounted thousands represented by these—confronted, for their country's sake, that awful uncertainty. Did they believe in your better world? Whether they did or not, this world was a reality, and dear to them.

I looked into one of the trenches in which workmen were laying foundations for the headstones, and saw the ends of the coffins protruding. It was silent and dark down there. Side by side the soldiers slept, as side by side they fought. I chose out one coffin from among the rest, and thought of him whose dust it contained,—your brother and mine, although we never knew him. I thought of him as a child, tenderly reared—for this. I thought of his home, his heart-life:—

"Had he a father?
Had he a mother?
Had he a sister?
Had he a brother?
Or was there a nearer one
Still, and a dearer one
Yet, than all other?"

I could not know: in this world, none will ever know. He sleeps with the undistinguishable multitude, and his headstone is lettered, "Unknown."

Eighteen loyal States are represented by the tenants of these graves. New York has the greatest number,—upwards of eight hundred; Pennsylvania comes next in order, having upwards of five hundred. Tall men from Maine, young braves from Wisconsin, heroes from every state between, met here to defend their country and their homes. Sons of Massachusetts fought for Massachusetts on Pennsylvania soil. If they had not fought, or if our armies had been annihilated there, the whole North would have been at the mercy of Lee's victorious legions. As Cemetery Hill was the pivot on which turned the fortunes of the battle, so Gettysburg itself was the pivot on which turned the destiny of the nation. Here the power of aggressive treason culminated; and from that memorable Fourth of July when the Rebel invaders, beaten in the three days' previous fight, stole away down the valleys and behind the mountains on their ignominious retreat,—from that day, signalized also by the fall of Vicksburg in the West, it waned and waned, until it was swept from the earth.

Cemetery Hill should be the first visited by the tourist of the battle-ground. Here a view of the entire field, and a clear understanding of the military operations of the three days, are best obtained. Looking north, away on your left lies Seminary Ridge, the scene of the first day's fight, in which the gallant Reynolds fell, and from which our troops were driven back in confusion through the town by overwhelming numbers, in the afternoon. Farther south spread the beautiful woods and vales that swarmed with Rebels on the second and third day, and from which they made such desperate charges upon our lines. On the right as you stand is Culp's Hill, the scene of Ewell's furious, but futile, attempts to flank us there. You are in the focus of a half-circle, from all points of which was poured in upon this now silent hill such an artillery fire as has seldom been concentrated upon one point of an open field in any of the great battles upon this planet. From this spot extend your observations as you please.
